C++ :

#include <iostream>
using namespace std;
int main() {
    int arr[7];
    for (int i = 0; i < 7; ++i) {
        cin >> arr[i];
    }
    int last = arr[6];
    for (int i = 6; i > 0; --i) {
        arr[i] = arr[i - 1];
    }
    arr[0] = last;
    for (int i = 0; i < 7; ++i) {
        cout << arr[i] << " ";
    }
    return 0;
}
